Definitions

  • the invention relates to a multi-plate clutch in the drive train of a motor vehicle.
  • Such multi-plate clutches are well known.
  • the multi-plate clutches consist of an outer disk carrier with a tooth profile on soft outer disk rotation and axially displaceable and an inner disk carrier with a tooth profile of soft Innlamellen rotatably and axially slidably disposed.
  • the outer and inner disks are mutually arranged and form a disk pack.
  • the disk pack is compressed by an actuator, whereby the slats are brought into frictional engagement.
  • the lamellae can be designed as steel lamellae and as lining-carrying lamellae, wherein upon actuation always one side of a lamella which has a covering is brought into frictional engagement with an adjacent lamella, which has no lining.
  • the actuator may for example be designed as a hydraulically operated piston. If such a multi-plate clutch is used as a starting clutch, especially at the beginning of torque transmission in the low torque range, the torque transmission behavior of the clutch is particularly sensitive to torque fluctuations, which affect disproportionately strong here, if the speed of the slipping clutch with its suggestions hits the natural frequency of the drive train. Thus, variations in the thickness of individual disks can cause torque fluctuations in the transmitted torque of the clutch, which can be transmitted to the entire subsequent drive train and can lead to a jerking of the vehicle or a jitter during startup.
  • From the EP 1 577 575 is also known to form an end plate of a disk pack in such a way that at high contact pressures as even as possible a pressure distribution is achieved.
  • Torque fluctuations of the transmitted torque occur especially when the two sides of the clutch rotate at different speeds, such as when starting, and the contact pressure fluctuates due to thickness variations of individual slats.
  • the torque is always increased when a survey in a lamella a survey in another lamella, which rotates at different speeds, happens, or when the piston or the opposite support of the plate package has a misalignment and the collection in a lamella through the piston or the opposite support point defined bottleneck happened.
  • the known resilient elements in the disk set serve to provide elasticity to bring the disk set, which torque irregularities due to thickness variations of individual slats can cushion.
  • a disadvantage of the known solutions is that the resilient elements rest only in an edge region of the adjacent lamella and thus an unequal distribution of pressure is introduced into the lamella packet. Although this inequality is still not critical at relatively low transmitted torques as when rolling, but not negligible.
  • the resilient elements are designed so weak that at a higher contact pressure, the elastic element is pressed flat on the adjacent blade. Upon actuation of the disk pack by means of the actuator, the force application radius which acts on the disk adjacent to the elastic element shifts gradually from the edge region to the radial center of the disk pack.
  • the object of the invention is to present a multi-plate clutch which, starting from the indicated prior art, has an improved introduction of force and thus an improved pressure distribution.
  • the elastic element is designed such that upon actuation of the disk pack, the elastic element comes into contact with the second edge region of the disk pack opposite the first edge region, the adjacent disk, and in the middle radius region the elastic element Element does not come to rest on the adjacent lamella. If the elastic element lies with its first edge region radially on the outside of the adjacent lamella, during actuation the second edge region, the radially inner region, is brought into abutment without the radially middle region coming into abutment. If the elastic element lies with its first edge region radially inward on the adjacent lamella, upon actuation the second edge region, the radially outer region, is brought into abutment without the radially middle region coming into abutment.
  • the advantage here is that the elastic element does not start, starting from the first adjacent edge region when operating the multi-plate clutch continuously over the middle to the opposite edge region to the adjacent blade, but that upon actuation of the multi-plate clutch first, the second edge region of the adjacent blade for concern comes, in the middle radius range, the elastic element does not come to rest on the adjacent blade. While it comes in the prior art only with complete concern of the elastic element on the adjacent blade and thus only at the end of the spring travel of the elastic element to a force on the second edge region, much earlier in the invention and thus still in the resilient region of the invention elastic element realized a force on the second edge region.
  • the average force application radius does not shift continuously towards the radial element of the disk pack toward the disk adjacent to the elastic element and only substantially reaches the force application radius of the actuator at the end of the spring travel of the elastic element.
  • the average force application radius is already at the concern of the reaches elastic element at the second edge region of the adjacent blade and then remains substantially constant over the remaining travel.
  • a particularly advantageous embodiment of the elastic element provides in this case that the course of the force application radius in the resilient region of the elastic element has a jump, whereas the course of the force in the resilient region is substantially linear.
  • the advantage here is that an advantageous control of the multi-plate clutch is possible by the linear force curve. Furthermore, a smooth transition of the force curve from the resilient region into the non-resilient region occurs when the elastic element rests virtually flat.
  • the elastic element is designed as an outer plate and is supported with a tooth profile in the outer plate carrier.
  • a radial guidance of the elastic element is ensured and, moreover, the elastic element can no longer rotate relative to the adjacent lamella.
  • both the elastic element and the adjacent lamella are formed as outer plates or as inner plates.
  • the elastic element is preferably formed such that the elastic element has a first region and a second region axially stepped therefrom, wherein the first region rests against the adjacent lamella when the lamina coupling is not actuated and the ratio between the first region and the second region is between 1/7 and 3/7 lies.
  • the first region corresponds to the first one adjacent edge region, whereas the second edge region forms only a part of the second region.
  • the first and second regions are defined so that the first and second regions together form the entire radial extension of the elastic element and thus the toothed region is associated with either the first or the second region.
  • the ratio of the first to the second range according to the invention ensures that upon actuation of the multi-plate clutch, the transmitted torque during starting, which is far lower than the maximum transmittable torque, substantially equal to the surfaces of the first and the second edge regions of the elastic element adjacent to the adjacent plate are big.
  • the axial step corresponds to between 10% and 90%, preferably between 10% and 50%, of the material thickness of the first region.
  • the advantage here is that the step can be stamped in the outer plate preferably made of sheet steel, and that the first region is not offset axially more than the axial material thickness in this area to the second region.
  • manufacturing tolerances of a stage are better controlled than a plate spring.
  • the second region of the elastic element lies in a plane parallel to the first region offset by the axial step.
  • the second area to the first area still has an angle in addition to the step, which is preferably between 1 ° and 10 °, most preferably between 1 ° and 5 °, so that the second area is inclined away from the adjacent louver and thus the second edge area is spaced farther than the step height of the axial step from the adjacent louver.
  • the axial thickness of the first and the second region is equally strong, so that the elastic element can be made of a flat disc.
  • the material thickness of the first region around the axial step is made thicker than the recessed second region.
  • a preferred arrangement of the elastic element in the disk set provides that the elastic element is arranged between the actuator and the first adjacent outer disk.
  • the advantage here is that the axial vibration capacity of the disk set is reduced. Axial vibrations that would be transmitted from the actuator to the disk pack are mitigated by the arranged between the actuator and the disk pack elastic element. As a result, both the torque fluctuations due to thickness variations of the fins are filtered away, as well as torque fluctuations due to axial vibrations or Anpresskraftschwankungen the actuator. The mass of the Disc pack is supported on the opposite fixed axial stop and thus decoupled from the oscillatory system.
  • the disk set lies directly on the actuator and the elastic element is arranged at the opposite end of the disk set, the torque fluctuations due to thickness variations of the disks are filtered away, but the mass of the disk set represents an oscillatory system which can be excited by axial vibrations of the actuator ,
  • a particularly preferred embodiment of the actuator provides that the actuator acts with a convex contact surface on the central radius region of the elastic element. It is advantageous here that the actuator acts on the region of the elastic element which, when the first and second edge regions are present, does not yet bear on the adjacent lamella, and thus still acts as a spring.
  • the elastic element according to the invention makes a tilting movement about the contact point of the actuator, the spherical contact surface serves that the contact point of the elastic element can roll on the actuator without tilting over an edge.
  • the actuator preferably engages with an end face on the elastic blade, which corresponds in its radial extent in approximately the material thickness of the slats.
  • the end face of the actuator can here be rounded or roof-shaped.
  • An alternative or additional embodiment of the invention provides that the elastic element on the actuator axially opposite side of the disk set between the last outer disk of the disk set and an axial shock, which axially supports the elastic element, is arranged.
  • the axial stop preferably acts on the middle radius region of the elastic element. In this case, as with the actuator-side arrangement of the elastic element, the force introduction radius or the Kraftabstützungsradius in the middle radius region, which still concerns spaced from the adjacent blade, and thus still resilient when concerns the first and second edge region.
  • Fig.1 is a multi-plate clutch 2 shown with an outer disk carrier 4, which has on the inner peripheral surface of a tooth profile 6, in which the outer disk 8 are arranged rotationally fixed but axially displaceable.
  • the inner disk carrier 10 has a toothed profile 12 on the outer peripheral surface, in which the inner disks 14 are arranged in a rotationally fixed but axially displaceable manner.
  • the inner fins 14 are formed here as covering-bearing fins and the outer fins 8 as steel fins. A reversal of lining and steel fins would also be conceivable.
  • the actuator is designed as an axially displaceable piston.
  • the disk pack is axially supported by an axial securing in the form of a snap ring 18, which is held in a groove in the outer disk carrier 4.
  • the supported on the snap ring end plate is thicker than the other outer plates to prevent deflection.
  • an elastic element 22 is arranged between the actuator 16 and the first outer fin 20, an elastic element 22 is arranged.
  • the axially elastic element 22 is held like the outer disk in the tooth profile 6 of the outer disk carrier 4.
  • the elastic element 22 has a corresponding tooth profile on the outer circumference.
  • the elastic element 22 rests against the adjacent outer lamella 20 only in the radially outer edge region.
  • the actuator rests with a crowned end face 24 in the middle radius region of the elastic element 22.
  • the elastic element 22 has an axial step 26, which adjoins the adjacent first edge region 28 limited. The step separates the first region, which corresponds to the first edge region 28, from the second region 30, which is exposed relative to the first region 28.
  • Fig. 2 is the multi-plate clutch of FIG. 1 shown in the actuated state.
  • the actuation state corresponds to a torque transmission capacity which is approximately in the range of 20 Nm to 50 Nm and is run through during startup.
  • the elastic element 22 is pressed by the actuator 16 against its spring force to the adjacent blade 20, so that the second, radially inner edge region 32, comes to rest on the blade 20.
  • the elastic element 22 now lies against the adjacent lamella 20 both in a region radially outward, the first edge region 28, and radially inward, the second edge region 32.
  • the average radius range of the elastic element 22 on which the actuator 16 acts does not abut against the adjacent lamella 20 and thus can still spring relative to the contact point of the actuator.
  • Fig. 3 is the same multi-plate clutch as in FIG. 1 and 2 shown, but at Nennanpresskraft of the actuator 16.
  • the second edge region 32 which rests against the adjacent blade 20 is greatly enlarged radially outward, whereas the first edge region 28 remains substantially constant.

  • Torque is transmitted from the drive unit to the two multi-disc clutches 102, 2 via the driver 60.
  • the elastic element 122 is arranged on the piston 126 opposite side of the disk set between the Axialabstützung 118 and the last fin of the disk set.
